Ok so Im sure I could dig up an answer to this question in old threads, but its taking me longer than expected. Im currently looking for a lift that will clear 315x75x16 tires. Rancho's 4 inch lift shows a max tire size of 35x12.50, while Rough Country's 6 inch lift shows a max of 35x12.50. Why is their a difference between tire clearance on different size lifts? Im assuming the Rancho 4 inch is actually bigger than is says, but honestly dont know enough about it. Any help with this question is greatly appreciated.
